Subject: [PATCH v4 0/6] Add display support on the stm32f746-disco board

The series adds support for the display on the stm32f746-disco board,
along with a generic patch that adds the "bpp" parameter to the stm-drm
module. The intention is to allow users to size, within certain limits,
the memory footprint required by the framebuffer.

Changes in v4:
- Use DTS property instead of module parameter to set the framebuffer bit depth.

Changes in v3:
- rename ltdc-pins-a-0 to ltdc-0.
- drop [4/6] dt-bindings: display: simple: add Rocktech RK043FN48H
  Applied to https://anongit.freedesktop.org/git/drm/drm-misc.git (drm-misc-next):
